Thanks for the info guys.

Actually, I've already been flying this setup in a Funtana 40, but the Funtana is just a little too much airplane for the 4120. It flew OK, but more like a moderately agile sport plane. I was looking for something a little bit more lively, which is why I decided to electrify my Twist. If my numbers are correct, the Twist setup will be about one pound lighter than the Funtana 40 setup.

I already have the system I described and (obviously) flown it as a 4S2P at 4200mAh (20 Continuous, 30 burst). I really don't want to invest in another battery pack right now.

I've got the Whattmeter from Astro Flight, and you're right, it's worth its weight in gold. I found that a 13x8 worked best for my setup on the Funtana 40, but it may not necessarily work on an electrified Twist.

My main question was, what was the pilots opinion of the electric Twist 40 if he were running an equivalent system to the one that I described.

Thanks,

Bob
